In the last years, Virtual Reality (VR) has been established itself as a highly promising media technology for reconstruction and presentation of cultural heritage sites to a wide audience. Virtual Reality enables not only an exploration of a single artefact but of many virtual objects spatially and temporally arranged into a single scene. The users enter an artificially created space and get a feeling of being a part of it. They can perceive and interact with the objects in the virtual environment in natural way. In this paper we propose a conceptual model of the VR module for the “Virtual Plaza for Immersive Representation of Bulgarian Cultural Heritage Sites”. It contains an analysis of the possible input data and the developed workflows to help experts from the cultural heritage domain to implement various scenarios for presentation of single artefacts and complete scene par of cultural heritage site using the benefits of Virtual Reality as visualization medium.

Background/Purpose: The myositis syndromes are rare systemic autoimmune diseases with poorly understood etiologies. We present the demographics, illness features and treatments of patients with juvenile dermatomyositis (JDM) who enrolled in a newly created national registry. Methods: Using a patient database from The Myositis Association and supplemental advertisements, a national registry of myositis patients was established. Between December 2010 and July 2012 questionnaires were mailed to 8847 myositis patients in the US and Canada. The questionnaire queried demographics, clinical features, environmental exposures, and quality of life. Descriptive statistics and multivariable logistic regression analysis were computed using GraphPad Prysm and SAS. Results: 1956 patients (22%) returned the questionnaire and consented to participate; 1806 who met probable or definite Bohan and Peter criteria for myositis were included (708 DM, 483 PM, 466 IBM, 139 JDM, 10 JPM); juvenile patients were diagnosed before age 18 years. Of the 139 JDM patients, the median age at diagnosis was 6.9 years and median disease duration at enrollment was 10.3 years. Most JDM patients were female (78%) and Non-Hispanic Caucasian (88%), and the remainder were Hispanic (6.5%), Asian (2.9%), multiple races (2.2%), and Black (0.7%). Patients or their parents often completed a graduate degree (23%) or college degree (29%). JDM patients were primarily diagnosed by a pediatric rheumatologist (48%), with adult and pediatric dermatologists (22%), pediatric neurologists and primary care physicians (11% each) diagnosing most of the remaining patients; 67% were under the care of a pediatric rheumatologist. JDM patients frequently had skin rashes as a major manifestation (86%); arthritis (35%) and dysphagia (32%) were also common, whereas lung disease (12%) was less frequent. An additional autoimmune disease was present in 18% of JDM patients, with JIA (8%) and SLE and celiac disease (3% each) the most frequ

A major limitation of the transmission-line matrix (TLM) method used to solve Maxwell's equations is the long computation time required. The TLM scattering calculations involved can, however, be viewed as parallel in nature. This paper describes an effort to reduce computational time by using an SIMD, DAP multiprocessor computer employed to solve a two-dimensional TLM electromagnetic field formulation. A parallel algorithm based on the TLM scattering algorithm is designed and implemented using FORTRAN-PLUS Enhanced on an AMT DAP 510 machine. Here the connectivity of the DAP is exploited to simulate the intrinsic scattering behaviour on which the TLM algorithm relies. The results show that parallel processing on an SIMD machine such as the DAP is advantageous, especially for higher-order mesh sizes.

RATIONALE FOR AN ADA SOFTWARE ENGINEERING ENVIRONMENT FOR NAVY MISSION CRITICAL APPLICATIONS

引用

NAVAL ENGINEERS JOURNAL 1984年第4期96卷 133-145页

作者： PAIGE, KK CONVERSE, RA USN LCdr. Kathleen K. Paige USN:graduated with a BA from the University of New Hampshire in 1970. She received her commission from Officer Candidate School in April 1971 and performed her first tour of duty with VFP-63 NAS Miramar. LCdr. Paige then received her MS from the Naval Post Graduate School in June 1976 and returned to San Diego to serve as Head Support Software Division at the Fleet Combat Direction System Support Activity. In May 1981 she reported to NA VSEA (PMS-408) where she served initially as Chairman of the NAVMAT Software Engineering Environment Working Group. She has been assigned as Deputy AN/UYK-43 Acquisition Manager since October 1981. LCdr. Paige was designated a fully qualified Engineering Duty Officer in December 1983. Robert A. Converse:is presently the Acquisition Manager for the Ada Language System/Navy (ALS/N) for the Naval Sea Systems Command Tactical Embedded Computer Resources Project. As such he is responsible for the definition and development of the ALS/N to be provided as a Navy standard computer programming system for Navy mission critical applications. Mr. Converse received a Bachelor of Science degree in Physics from Wheaton College Wheaton II. He spent fourteen years with the Naval Underwater Systems Center Newport Rhode Island during which time he designed and developed the Fortran compiler for the Navy Standard AN/UYK-7 computer. Also during that period he received a Master of Science degree in Computer Science from the University of Rhode Island. His thesis for that degree was entitled “Optimization Techniques for the NUSC Fortran Cross-Compiler”. Mr. Converse started his involvement with the Ada program in 1975 with the initial “Strawman” requirements review. Subsequently he was named as the Navy Ada Distinguished Reviewer and was intimately involved in the selection and refinement of the Ada language as it evolved to become ANSI/MIL-STD-1815A.

The U.S. Navy introduced the use of digital computers in mission critical applications over a quarter of a century ago. Today, virtually every system in the current and planned Navy inventory makes extensive use of computer technology. Computers embedded in mission critical Navy systems are integral to our strategic and tactical defense capabilities. Thus, the military power of the U.S. Navy is inextricably tied to the use of programmable digital computers. The computer program is the essential element that embodies the system “intelligence”. In addition, it provides the flexibility to respond to changing threats and requirements. However, this very flexibility and capability poses a host of difficulties hindering full realization of the advantages. This paper describes the lessons learned about computer program development over the past twenty five years and discusses a software engineering process that addresses these lessons. It then describes how Ada and its related Ada programming Support and Run-Time Environments foster this software engineering process to improve computer program productivity and achieve greater system reliability and adaptibility. Finally, the paper discusses how the use of Ada and its environments can enhance the interoperability and transferability of computer programs among Navy projects and significantly reduce overall life cycle costs for Navy mission critical computer programs.

COMBAT SYSTEM ENGINEERING - A RETURN TO FUNDAMENTALS

引用

NAVAL ENGINEERS JOURNAL 1993年第3期105卷 61-69页

作者： MITTURA, A KARP, MS PE Andrew Mittura:is currently a senior program engineer with SYSCON Corp. He began his career in the Combat System Installation and Integration Office of NavSea in 1978. He has worked as a system engineer on the Seafire program at NSWCDD on the NATO Anti-air Warfare Program while at FMC Corporation and for the past four years on the Aegis Combat System with SYSCON. Current efforts include performance assessment studies of the Aegis combat system and combat system architecture and connectivity analysis. Mr. Mittura received a B.S. in electrical engineering from Penn State University in 1978 and an M.S. in engineering management from Catholic University of America in 1982. He is a licensed professional engineer with the State of Virginia. Mitchel S. Karp:cofounded K&K Software Engineering Inc. in February 1970. He is currently secretary/treasurer and senior system engineer. His involvement in combat systems began with NTDS in 1963. He has been involved in the Aegis Program since 1968 and has worked in all aspects of combat system development including computer programming tactical analysis software development and management. He has given several seminars on real-time software development and documentation. He currently is working under contracts to NSWCDD in the areas of combat system architecture and connectivity configuration management and documentation. Mr. Karp received a B.S. in engineering physics from Lehigh University in 1958.

The Navy's focus has shifted from global war scenarios to preparedness for the prospect of involvement in regional, littoral contingencies and conflicts. Operationally, shipboard personnel will need the ability to shift focus from the combat system multimission roles to that of only a single mission. From a development perspective, combat systems must accommodate a continual infusion of technology in a budget constrained environment. Combat system architecture is the single most important feature affecting combat system flexibility, from both an operational and developmental aspect. There is a fundamental partitioning of combat svstem functions into detect, command, and engage in a horizontal integration approach that enhances this needed flexibilitv. This fundamental partitioning is currently applied to individual weapon systems, but not to combat svstems as a whole. Instead, self-contained weapon systems are often developed and then vertically integrated to form a combat svstem, causing reduced flexibility. The battle organization is the principal driving requirement for combat system architecture. This paper shows that that the battle organization is best supported by a horizontally integrated combat system of detect, command, and engage. It concludes that a horizontally integrated combat svstem architecture of detect, command, and engage should be a candidate for future combat systems.

This paper presents a design method of control systems such that a designer can flexibly take account of tradeoffs between evaluated uncertainty ranges and the level of control performance. The problem is reduced to a BMI problem and approximately solved by LMIs. The convergence of the proposed approximation is proved in a modified sense. A numerical example shows the effectiveness of the proposed method in comparison with the standard robust control.

This paper explores the concept of an underwater robot manipulator mounted on an unmanned submersible for the purpose of doing some undersea tasks of interest to the U.S. Navy. The robot concept is compared with other methods of doing work underwater and its strengths and weaknesses are enumerated. Such a robot would be able to do only simple, well‐defined tasks, but it would probably be the most economical way of doing those jobs which are within its competence. The jobs which such a device might be able to do are listed and evaluated in terms of how easy or difficult they are for a robot to do. From this analysis some conclusions are drawn about what capabilities are needed in such a robot. It is concluded that speed of operation is not critical (In contrast to robots which are intended for industrial jobs), but that the ability to cope with unexpected conditions and to recover from mistakes is very important. Next, existing robot technology and past research***are discussed and evaluated in terms of the needs of an underwater naval robot. Gaps in the technology are identified, and, finally, me suggestions for research are given. © 1980 American Society of Naval Engineers
